UNITED STATES PATENT OFFICE JOHN A. WARE, OF MORRIS, ILLINOIS.

.IMPROVEMENT IN FOLDING CHAIRS.

Specification forming part of Letters Patent No. l87,944,'dated February27, 1877 application filed December 16,1876.

To all whom it may concern Be it known that I, JOHN A. WARE, of Morris,in the county of Grundy and State of Illinois, have invented a new andImproved Folding Chair; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawing, forming part of this specification, in which-Figure 1 is a side elevation of the chair disposed for use, partly insection, and with a modification of the toggle arms shown in dottedlines. Fig. 2 is a side elevation of the chair when folded, butsupported upon its legs.

Fig. 3 is a plan view, partly in section, of the chair when folded andlaid down with its rear side up.

My invention relates to certain improvements in folding chairs; and itconsists in a chair having the rear legs and back made in one piece,with a seat hinged to the same at the rear and free to fold upwardly atits front, in connection with which elements are arranged a set of frontlegs with tenons at their upper ends, which enter mortises in thechairseat, the said front legs being connected with the seat and back bymeans of side braces pivoted to the front legs and the middle part ofthe seat, and the back of the chair, and provided with anupwardly-folding to'gglejoint, whereby the parts of the chair may befolded compactly, and in such manner as to stand alone upon its fourlegs, as hereinafter more fully described.

In the drawing, A represents the back of the chair, whose side bars areextended to form the rear legs B. O is the seat, which is cut away onthe sides at the rear, and is hinged or pivoted at these points betweenthe back or rear legs of the chair at a. D are the front legs, which arerigidly fastened to each other, and are provided at the top with tenonsb, which enter corresponding recesses or mortises b in the under frontedge of the seat, to hold the same stiffly in position when disposed foruse. E are the side braces, which are pivoted in front to the front legsat o, and extending rearwardly and upwardly are pivoted to the middleportion of the seat at c, and also to the back at 0 a toggle-joint beingformed in the said braces between the points 0 0 which permit the upwardbending of the brace and the folding of the parts of the chair. Thistoggle-joint is formed by recessing the under side of the brace, andpivoting therein a metallic bar, d, which latter is at its rear end bentat right angles, and then bent aroundin tubular form, as at d, whichportion passes through the sides of the back of the chair to formpivots, upon which the bars move without separate devices for thispurpose.

As a modification of my invention I may form the toggle-joint orstiffening device in the brace below the seat, as indicated in dottedlines, Fig. 1, and connect the seat with the same by means of a link orother equivalent device.

With the chair constructed as thus described it will be seen that thechair can be folded compactly and with the bottom of all its legs in thesame plane, thus enabling the chair to stand alone even when folded.

Having thus described my invention, what I claim as new is 1. Thecombination, with the back and rear legs A B, of the seat 0, pivoted tothe same at a, and having recesses b, the front legs D having tenons b,and the side braces E, pivoted to the front legs at c, to the seat at c,and to the back at 0 and having an upwardlyfolding toggle-joint,substantially as and for the purpose described.

2. The combination, with the back A, of the bar 11, bent at right anglesand then in tubular form, d, to form a pivot, substantially as and forthe purpose described.
